ANDREW KAYSER, OF FULTON, MISSOURI.

LARD-LAMP.

Specification of Letters Patent No. 4,154, dated August 20, 1845.

To all whom it may concern:

Be it known that I, ANDREW KAYSER, of

Fulton, in the county of Callaway and State of Missouri, have invented anew and useful Improvement in the Manner of Constructing Lamps for theBurning of Lard and other Fatty or Oleoaginous Substances; and I dohereby declare that the following is a full and exact descriptionthereof.

In lamps for burning lard and other concrete substances there is usuallyconsiderable difficulty in the using of a wick of much length, as inWithdrawing the burner the wick is frequently left behind; and when thewick is short the supply by capillary attraction fails, and the lampburns dimly and wastefully. To obviate this difficulty, I aflix awick-receiver to the lower end of the burner tube, or tubes, withinwhich the lower end of the wick may be doubled up, or coiled, so thatone of two or three times the ordinary length may be inserted. Thewick-receiver must be of such size as will admit of its passing into thereservoir, through the neck, or opening, in the upper part of the lamp.By this arrangement, the burner, with its wick, may be readily removedeven while the material in the lamp is in a hard state, as the burnermay be loosened by twisting it around without disturbing the wick in theslightest degree.

The accompanying drawing is a perspective representation of my burner;a, a, being the wick tubes, and b, the collar that is to fit into theneck of the lamp; 0, 0, is the wick-receiver, which consists of a box,or cup, that is soldered on to the lower end of the wick tubes, is openat top and has perforations, cl, (Z, through its sides. Within this box,or cup, the lower portion of the wick, e, e, is received, and remainsuntil drawn up in the ordinary burning of the lamp.

my improvement in the lamp for burning lard and other fatty substances,what I claim therein as new, and desire to secure by Letters Patent, is

The employment of a wick-receiver, which is attached to the lower end ofthe wicktube, or tubes, for the purpose of containing a length of wickthat may be coiled up therein, in the manner, and with the intention,herein made known.
